MANUAL_CURATION
via cbclaw_review_fix
Corrected from CHEBI:78018 (dodecylphosphocholine — a detergent, not a peptone). Bacto-tryptone is Difco/BD's brand of tryptone. Mapped to the same FOODON parent as Tryptone.yaml; dropped wrong CAS-RN 53949-18-1.
CURATOR_JUDGMENT
via manual review of MICRO ontology coverage
Tryptone is pancreatic digest of casein. MICRO has the exact term; FOODON:03315719 is the parent class "mammalian milk protein (hydrolyzed)" which is technically true but loses specificity.
